I heard over the weekend, from a fellow DC creator, that they’d been told why Robinson left the book. As had been presumed, there were plans for a second Earth 2 book, but I understand that DC had chosen someone rather than Robinson to write it. And since Earth 2 was a book that Robinson takes some pride in, and some credit for its barnstorming success, bucking the trend of other new books introduced to the New 52, he took that as an affront. And so decided to walk from the original Earth 2 book.

I stress that this is only one version, and is hearsay from another DC creator. And that Bleeding Cool was unable to reach Robinson for comment. But it does fit into other, confirmed narratives, concerning creator relations at the publisher.
